- BEAM HEAD.

Application filed April 18, 1922i. Serial No. 554,909. 7

To all whom it mctyjconcern [Be it known that'Ij FRANK Mossnnne, a

citizen of the United States, residing at Attleboro, in the county ofBristol andState of Massachusetts, havejnvented certain new and usefulImprovements in Beam Heads of which the following is; aspecification.

This invention relates to an improvement is the construction of beamheads andthe like by which the head is adapted to be adjustablyconnected-to a beam-or body on which 1 yarn or other 'material may bewound; and theobje'ct of'thisinventionis to provide a he'ad'of thischaracter having a hub member adjustably mounted thereon whereby the hubmay be contracted and moved radially bodily to bind the head in adjustedposition upon the-beam.

A further object of the invention is to provide means whereby the endsof the radiating arms of the hub sections'are adj ust ably attached tothe head-plate instead of being permanently or fixedly attached theretoas has heretofore been the case by which construction these radiatingarms maybe moved radially and [so permit a greater range of movement tocause the hub member to betterfit and be more effectually clamped aboutthe beam to connect the head thereto.

With these and other objects in view, the invention'consists ofcertainnovel features of construction, as 'will' be more fully described, andparticularly pointedout inthe appended claims. .7

In the accompanying drawings:

Figure l is aside elevation illustrating a pair'of my improved beamheadsadjustably mounted upon a beam. r i

Figure 2 is a faceview ofmyimproved beam-head showing the generalarrange-- ment of thedifferen't sections of the hub.

Figure 3 is a section. on line 3-3 of Figure 2 showing improved meansfor de tacha-bly securing the middle portion ofthe hub section to theplate.

Figure 4 is a perspective view showing one of the lugs which is employedin adjustably securing the hubisections, thebody portion of whichjug isadapted to be weld'ed to the head. i

Fignre 5 is' a perspective view of one of the hub sections detachedshowing the lugreceivingslots therein.

into which the finger portion of the lug'is adjustably inserted. Figure7 is a detail showing the headed inner end ofoneiof' the lugs.

It is foundin practice in the construction ofbeam-heads of thischaracter necessary to so construct the hubportion of the head thatitmay be contracted to'bind the head in adjusted position on the beam,and one practical construction is to form the same 111 sections havingcooperating rad ating arms, which arms have heretofore, had

some portion fixedly attached to the head and by which constructionthecontracting action of the hub was materially limited. My presentimproved construction is the provision of means whereby the differentsections are mounted to "float upon'the head and are adapted to beadjusted bodily to contract the hub securely about the beam, and thefollowing is a detailed description accomplished I With reference to'thedrawings, 10 designates the usual body portion of a warp- 'of one meansby which this result may be 77 beamqwhich in this particular case isusually 1' constructed Of'WOOd but which of course,

may be made of any suitable material.

In the making of beams of this character the head members 11 arepreferably so con structed that they may be adjusted longi tudinallyalong the length of'the body por eon of the beam in order to regulateits working length.

It is also one of the objects of'the invention to construct both thehead-plate and the hub sections of sheet metalwhereby the" whole may bemade very light in weight and thehub sufficiently yieldable to bereadily contracted to clamp the same upon the body portion'and holdthe'head in any adjusted positionthereon. l

The periphery of this head-plate'is preferably rolled outwardlyas at 12;to provide a stiffening flange therefor, and the center of this plate iscut out as at 13 to permit the passage of the end of the beam therethrough.

The hub member 14' is preferably. constructed of four separate sections,each having a body portion 16 formed on the arclof a circle withradiatingv end members 17 all set edgeways against the-outer faceofthehead-plate, and at right angles to each other. 1

The radiating end members of each section are spaced apart as at. 1 8and the end of each section is pierced as at 19 to receive the reducedneck portion 20 of the lug 21 to slide thereinto, the outer end of thisreduced neck portion being headed over after having been positioned inthe slot to prevent the.

outer ends of these opposite end members from drawing inward toward eachother under tension of the binding bolt 24, presently described, thebody portion of the lug being then permanently secured, preferably by aspot-welding operation, to the outer face of the head-plate therebyeliminating the usual riveting operation employed for this purpose. v

The body portion of each section is also slotted as at 22, to slidablyreceive the reduced ends of the lugs 23. ,7

In order to contract these hub members to bind the head in adjustedposition on the beam I have provided binding bolts 24 which pass throughthe adjacent arms 17 of the different hub sections whereby'by setting upthe nuts on these bolts the different sections are caused to move bodilyinwardly tobecontracted and so lock the head see curely to the beam. f

In some instances the head-plate itself is formed in sections in whichcase I provide guide fingers 25 and 26 and spot weld the differentsections to hold the plate sections in alignment or in the same planewith each other.

By my improved construction of beam head I am enabled to do away withthe usual cumbersome cast iron hub which heretofore has been employedfor this purpose and have provided one which is much lighter in weight,less expensive to construct, is stronger and more durable and by its usethe contractible members vof the'hub may permanently secured to theouter face of the head-plate by a welding operation whereby the inner orworking face offthe head is leftplain and smooth, then-again by myparticular construction the hub sections having radiating arms are setedgeways against the face of the head-plate. the plate is materiallystiffened and one of comparatively light weight may be employed, and bythe use, of my improved head-plate the hub may be readily contracted bya free bodily movement of its sections to grip and bind the bodyportionv ,of thebeam and hold the head in any adjustedposition along itslength. a

The foregoing description is directed solely towards the constructionillustrated, butl desire it ,to be understood that I reservetheprivilege. ofaresorting to all the mechanical: changesto which thedevice is susceptible. the invention being defined, and limited onlybythe terms of the appended claims. 7 Y Y Iclaimt 1.
